  The present invention relates generally to pneumatic material transfer systems, such as partial vacuum transfer systems, and more particularly to waste collection and transfer, such as household waste transfer.

  Systems in which waste is conveyed through piping by suction are known in the art. In these systems, waste is transported by suction over long distances in the piping. In particular, the device is used for transporting waste in various facilities. It is typical for these systems that a partial vacuum device is used to achieve the pressure differential, in which a partial vacuum is achieved in the transport pipe by a partial vacuum generator, such as a vacuum pump or ejector device. The The conveying pipe usually comprises at least one valve means, and the replacement air entering the conveying pipe is adjusted by opening and closing the valve means.

  The solution according to the invention has many important advantages. With the solution according to the invention, the initial cost of the waste system in a wide range of construction projects can be better distributed over a longer span than before. The system can be expanded modularly by subsystems. If desired, this solution allows a temporary partial vacuum generator to be placed in connection with each subsystem, or a wider system to achieve the suction required for use of this system. The system offers the possibility of using only the partial vacuum generator. In this case, the waste can be transported for further processing from the waste storage tank of the subsystem in the desired transport method. The system according to the present invention allows for reliable operation and in addition provides the possibility of being easily delegated to a backup system in the event of a main system failure. By using the suction / pressure of the material transport system, waste is transported, for example, to the tank of the transport means. In this case, the transportation means can be any transportation means provided that it has a suitable tank such as a container or the like. By configuring the piping of the system so as to include a circulation path through which at least part of the carrier air circulates, the amount of exhaust air can be reduced. At the same time, the energy consumption of the system is reduced. By maintaining the partial vacuum and at the same time maintaining the blowout, it is possible to achieve an effective circulation of the carrier air in the circulation path and a conveyance of material in the carrier pipe. With the solution according to the present invention, it is possible to substantially reduce the amount of exhaust air, and at the same time reduce possible dust problems and particulate problems in the exhaust pipe.

FIG. 7 shows the five subsystems 1 (I, II, III, IV, V) and the waste station 2 and the necessary transfer piping 10, 11, 12, 114 between the subsystem and the waste station. The overall system comprising

  FIG. 1 shows a subsystem 1 comprising a material transport pipe 100, with at least one, usually many input points 61 arranged along the side of the material transport pipe. The input point 61 is a material intended to be transported, more specifically, a waste material feeding station. The material intended to be transported from this station, more specifically, waste material such as household waste. Is fed into the transport system. The infeed station can also be a waste chute, in which material is fed from the input openings of various floors of the building. The system can comprise a plurality of infeed stations 61 from which material intended to be conveyed is fed into the conveying piping 100, 100A, 100B, 100C, 100D, 100E, 100F. In the drawing, the feeding station 61 is indicated by a dot. In this case, the material can be transported from the charging point into the transport pipe by opening and closing the shut-off means such as the valve means 60 connected to the feeding station. FIG. 1a shows in more detail one input point 61 and a discharge valve 60 at this input point used in the system according to the invention. The injection point is connected to the transport pipe 100 on the valve side. Usually, the transfer pipe is provided with a main transfer pipe 100, a plurality of branch transfer pipes 100A, 100B, 100C, 100D, 100E, and 100F can be connected to the main transfer pipe, and a plurality of infeed stations 61 are provided. It is also possible to connect to a branch conveyance pipe. The embodiment of FIG. 1 includes six branch transfer pipes 100A, 100B, 100C, 100D, 100F, 100E, and 100F connected to the main transfer pipe 100. The fed material is transported to the storage tank 105 of the subsystem 1 along the transport pipes 100, 100A, 100B, 100C, 100D, 100E, and 100F. The accumulation tank 105 can be arranged in a waste space 120 of the subsystem 1, for example, a waste space unique to a block.

  In the illustrated embodiment, a pipe 107 is connected to its upper part of the storage tank 105, which can be connected to a partial vacuum source. According to one embodiment, the partial vacuum source is a partial vacuum generator 25, 26 located at the waste station 2, and the suction side of this partial vacuum generator is connected via pipes 107, 118, 114, 10. The storage tank 105 can be connected to the transfer pipes 100, 100A, 100B, 100C, 100D, 100E, and 100F via these pipes. Correspondingly, the lower part of the storage tank 105 can be connected to the transfer pipe 10 via the pipe 114. The pipe 114 includes valve means 115 between the accumulation tank 105 and the pipe 118.

  In addition, the subsystem 1 can comprise means for connecting to the subsystem and placing its own separate partial vacuum source. A medium path 107 to the first connection 113 is arranged from the accumulation tank 105, that is, from the upper part of the accumulation tank in FIG. A second medium path 116 to the second connection 121 is arranged from the bottom of the storage tank. The second medium path 116 is provided with valve means 117 between the accumulation tank 105 and the second connection part 121. In the illustrated embodiment, the second media path 116 leaves the pipe 114 between the storage tank 105 and the valve 115.

  In the subsystem, the working path of suction to the accumulation tank 105 can be changed to the upper part of the accumulation tank via the path 107 or to the lower part of the accumulation tank via the path 114.

  Hereinafter, the operation of the system will be described with reference to FIGS. FIG. 1 illustrates a situation in which it is desirable to empty one or more material input points of the branch conveying pipe 100A.

  When the suction sides of the partial vacuum generators 25 and 26 are connected to the accumulation tank directly or via a conveyance air duct, the discharge end of the conveyance pipe 100 is further connected to the accumulation tank, and a partial vacuum is generated in the conveyance pipe 100. Generated. In this case, suction acts in the transport pipe 100 via the medium path 107 connected to the accumulation tank. An area valve 101A is located between the main transport pipe 100 and the branch transport pipe 100A and is open at this stage of operation. In this case, the suction can act also in the branch conveyance pipe 100A. In the case according to the figure, when the valve means 60 at this point is open at the input point 61, the batch of material intended to be transported is transferred into the branch transport pipe 100A and further forward into the main transport pipe 100. The For example, when the valve 60 to the transport pipe is opened, possible replacement air flows into the transport pipe via the input point 61. When the entry point valve 60 is closed, the line valve 102A can be opened to accept replacement air into the transport pipe, or the line valve 102A is opened when the material is emptied. In this case, the material of the feed container 61 that is emptied is dropped into the air stream moving in the transport pipe 100A.

  Waste material is transported to the storage tank 105 along the transport pipes 100A, 100, where the transport air is separated from the waste material, and the waste material remains in the storage tank 105 (FIG. 2).

  When all entry points intended to be emptied are emptied and material is conveyed from the branch conveying pipe 100A into the conveying pipe 100, the area valve 101A can be closed and then emptied. The area valve 101B (FIG. 3) of the branch transport pipe 100B in the area intended to be opened can be opened. After the contents of the entry point of this branch conveyance pipe are emptied and moved into the conveyance pipes 100B and 100 by a method corresponding to the method described above with reference to FIGS. 1 and 2, the inside of the pipe is conveyed forward to the accumulation tank 105. The area valve 101B of the branch transport pipe is closed and it is possible to move to the next area that is emptied by opening the area valve 101C (FIG. 4) of the branch transport pipe 100C, for example.

  If the storage tank is full and it is desirable to empty the storage tank and move it forward into a transfer pipe 10 or another reservoir, such as a transfer tanker (FIG. 5), the subsystem 104 can be closed by closing the valve 104. The connection from the transfer pipe 100 to the storage tank 105 is closed. Also, the valve means 119 closes the connection from the partial vacuum generators 25, 26 to the medium path 107 to the top of the storage tank. The suction effect is transmitted to the path 114 located at the bottom of the accumulation tank, where the accumulation tank material begins to move from the accumulation tank through the path 114 into the transport pipe 10. When valves 108 and 110 are in the open position, replacement air is received in the upper portion of accumulation tank 105 via replacement air pipe 109 and media path 107.

  In the figure, the material conveying direction and the air traveling direction are indicated by arrows.

  The take-out device 106 such as a worm conveyor driven by the drive device M can assist the conveyance of the material from the accumulation tank 105.

  Alternatively, the material can be transported from the storage tank 105 via the pipe 116 and the connection 121. In this case, suction is achieved via the connecting part 121, for example, by a portable partial vacuum generator (not shown). In this operating phase, the valve 115 in the path 114 is closed and the material is guided through the connection 121.

  It is conceivable that the material can be removed from the accumulation tank more efficiently by circulating the carrier air to the upper part of the accumulation tank through the connection portion 113 and the path 107. In this case, the blowing side of the partial vacuum generator is connected to the path 107. In this case, the use of blowout with suction is an aid and enhances the transfer of material from the storage tank into the transfer pipe.

In this separation device, for example, the material conveyed due to the reduced speed and centrifugal force is separated from the conveying air. For example, according to need, the separated material is removed from the separation device 20 to a material container, such as a waste container 40, or removed for further processing. There can be many separators 20, 21 and there are two, for example particle separators, a first separator 20 and a second separator 21, as in FIGS. 8a, 8b. be able to.

  The first separation device 20 is connected to the second separation device 21 by a duct 22 and is connected to means 25, 26 for proceeding to form a partial vacuum in the transport pipe by means of the transport air ducts 23, 24. . In the illustrated embodiment, the means for creating a partial vacuum includes pump devices 25, 26, such as vacuum pump units.

The vacuum pump unit includes at least one vacuum pump 25, 26 driven by a drive device M. The system includes means for circulating the carrier air in the circulation path, and a part of the circulation path is formed by at least a part of the conveyance pipe 10.

In FIG. 8a, the pipe 11 is the inlet pipe of the transport pipe 10, the valve 14 of this pipe 11 is open to the pipe 19, which leads the path to the front separating device 20. The blow-off side of the partial vacuum pump device can be connected by a transport pipe so as to blow out into the outlet pipe 12. The first end 11 of the transport pipe 10, i.e. the inlet pipe of Fig. 8a, is connected to the suction side of the pump device via a separating means, and the second end 12, i.e. the outlet side of Fig. 8a, is connected to the pump device. In this case, there is a medium connecting portion from the blowing side of the pump device to the second end portion 12 of the annular conveying pipe.

  In the system shown by FIG. 7, the main transport pipe 10 is annular, in which case suction is configured via the first end 11 of the main transport pipe or configured via the second end 12. Depending on what is done, the circulation of the carrier air in the main carrier pipe 10 can be changed.
